Battery recharging system and method for electronic cameras |
摘要 |
A rechargeable battery in an electronic camera is charged without additionally providing the camera with a power generating device. When a power-supply switch of the camera is turned off, a diaphragm and a shutter are opened and a taking lens is controlled so as to set focus to infinity. Signal charge that has accumulated in a CCD is output as a charging current, and the rechargeable battery is charged by a power-supply control circuit.
